WHEEL.

SPECIFICATION forming part of Letters Patent N0. 769,361, dated September 6, 1904.

' Application filed May 19, 1904:. Serial No. 208,746. I (No model.)

T0 aZZ whom it may concern:

zen of the United States, residing at Los Angeles,in the county of Los Angeles and State of California, have invented new and useful lowing is a specification.

My invention relates to rotating wheels which carry a superstructure; andthe object thereof is to provide means to reduce the jar into a hole or running over an obstruction. I accomplish this object by the means de scribed herein and illustrated in the acc0m' panying drawings, in which Figure 1 is a central longitudinal section of the hub of a vehicle-Wheel equipped with my jar-reducing mechanism, a portion of the axle and spokes being shown in elevation. Fig. 2 is a cross-section on the line 22 of Fig. 1 looking toward the spokes. v

In the drawings, A is the axle of the vehicle and is provided with. the usual wheel-retaining nut B. Where the axle tapers, I secure a tapered bushing 0 upon the tapered end of the axle, which bushing is provided with anannular flange C, which is preferably located on a line with the spokes D. The

outside'of this bushing is preferably cyline' drical.

the hub E is chambered to form spring-re.

On each side of this annular flange taining chambers F and G, in which are mounted spiral springs H and I, which surround the bushing and reduce the jar of the side thrust caused by the wheel dropping suddenly into a chuck-hole or running over an obstruction or turning a corner rapidly. Where the end of the axle. is straight, the bushing is preferably not tapered.

Lugs C may be provided on the bushing, which enter grooves E in the hub to prevent the bushing from rotating in the hub. Lugs C may also be provided on the bushing to keep the ends of the springs in contact with the flange, and thereby prevent the springs from rattling.

By this construction the jar of the side 7 thrust of a traveling vehicle is greatly re- Be it known that I, JAMES S. SrEvENs,a citiduced and in most cases entirely eliminated. The hub is preferably made of malleable 'castmetal and is cast in two parts, which are secured together by rivets S. Improvements in Wheels, of which the fol- Having described my invention, what I claim as new, and desire'to secure by Letters Patent, is

' 1. In a vehicle-wheel a hub having a central bore-adapted to fit upon anvaxle, said hub being divided transversely in the center thereof andha'vingan annular chamber in the center of said hub, said chamber. being larger than the bore through said hub; means to secure the parts of said hub together; a bushing having a flange projecting into the annular chamber of the hub; spiral springs on said bushing in said annular chamber one on each side of the-flange thereof.

2. In a vehicle-wheel the herein-described v ing hub H transversely divided in the center thereof andhaving annular chamber G in the center'thereof; rivets S securing the parts of said -hub together. bushing C having a central annular flange projecting into said chamberG and dividing the same into two parts;-

spiralsprings H surrounding said bushing and lying in said chamber G; lugs C adjacent to flange C and adapted to secure one end of the springs H in contact with said flan e C" lu s C on the outer side of said y l I: I n ;bush1ng, saidhub having a groove therem for thereception of said last-named lugs.

' In witness that I claim the foregoing I have hereunto subscribed my name this 13th day of May, 1904:.
